Sorry, but I'm still on the fence.

ME3 makes that work with two factors that often get overlooked; firstly, it's all co-op play against AI enemies, so no getting beat by bigger and tougher players, and secondly XP gets divided up equally among the team so you don't get the higher-level characters "hogging" all the advancement. It really does encourage team play that way.

-- Steve's seen some griefing in ME3, but not nearly as much as in other titles.
